The syntax editor can be disabled or enabled by modifying the

next to a line of code that contains an error by modifying the

the sys_properties.list, refer to [Available system properties](https://www.servicenow.com/docs/access?context=r_AvailableSystemProperties&version=yokohama&pubname=yokohama-platform-administration&ft:locale=en-US).
